phreaknet.sh, phreakscript_update.sh: Improve script portability.

Several portability fixes and some other general maintenance:

* Use curl instead of wget on systems with BusyBox. As part of this,
  use $WGET instead of wget wherever possible.
* Fix Asterisk PID detection on systems with BusyBox.
* Use more canonical path for rasterisk binary.
* If --offline is specified, do not check if a newer version of
  PhreakScript is available (since we should not be using the Internet).
* Add missing slipstream call for res_telos_1a2.
